Homebuilt ROVs Forum

Yep got I it wrong. Checked my connections on the ROV and here is how it is actually connected.

I could have got it wrong, I'll check my connections and verify.

Sea water actually

Here is how I connected my Arduino Nano's to the RS 485 modules.

Here is my latest footage taken today. The redesigned end cap and thru hull connections worked great and there was very little noise in the camera feed (haven't fitted baluns yet) and control of the ROV was good. I still had issues getting smooth control of the ROV and this is part due to my design,...

I made a new end cap over the last week and instead of using solid copper wire set in epoxy for my through hull connections I decided to try the alternative method of using insulated wire with the insulation stripped back in a section which is set in epoxy. I tested it this evening down to 50m and w...

Hi there, I have had a look at your code and it seems you have only included the 'Master Code' which is for the ROV topside controller only. Where is the DHT11 sensor? Is in topside in the control box or mounted inside the ROV? The Techmonkey code uses 2 x arduinos communicating with each other. The...

Thanks for your ideas, I will definitely add video baluns. My thru hull connections are a bit of a dogs breakfast and I think I need to tidy them up and ensure water is not interfering with signal, I'll try measuring the resistance too. I'm also wondering if the motors draw more power the deeper it ...

This was an 11m deep sea water test. The issues I encountered were that as the ROV went deeper, the camera feed to the surface got progressively worse and operating the motors interfered with the feed. The control of motors was also sketchy at 11m. Recording to SD card on the onboard dash cam was fi...

I had a couple of enquiries about my ROV, so I thought I post some photo's and name components etc. My design is heavily based on Hamish Troloves design from his website http://www.techmonkeybusiness.com/rov-control-sketches-fourth-edition.html with a few changes in code and components. This build i...
